What’s that strange feeling? Almost like I’ve seen a ghost. Oh, Google Glass isn’t dead after all? That’ll be it. There have been recent signs that the seemingly abandoned experimental wearable might be making a return in one form or another, more than 2 years after the Glass Explorer Program officially ended. The first was an update to the MyGlass app last month, after lying dormant for nearly 3 years. This was followed the next day by a mysterious firmware update making its way to any Glass units still in use.
